Product details

Overview:

The KX20E series rail mounted single-phase energy meter is a new generation of miniature energy meters developed by our company based on years of experience in meter design. The miniaturized structure facilitates its use with miniature circuit breakers and is installed in terminal distribution boxes, providing an effective solution for energy metering in low-voltage distribution terminals. Widely applicable to buildings, shopping malls, exhibition centers, schools, airports, ports, and factories.

The KX20E series rail mounted electric energy meter is divided into three types: basic type, enhanced type, and multiple rate type. The basic type can measure four quadrant electrical energy, while the enhanced type not only measures four quadrant electrical energy, but also adds measurement of electrical parameters such as voltage and current. The multi rate type provides multi rate energy metering and measurement functions for all electrical parameters. All three types can be equipped with one switch output and one RS485 communication function for remote control and data acquisition.

The electric energy meter adopts LCD display, which can set parameters such as clock and rate period, and has the function of outputting electric energy pulses; The use of RS485 communication interface for data exchange with the upper computer greatly facilitates the automation management of electricity consumption. This electric energy meter has the advantages of small size, high accuracy, good reliability, and easy installation. Its performance indicators meet the technical requirements of international GB/T17215, GB/T17883, and DL/T614 for electric energy meters in the power industry.
